INTRODUCTION
The phenomenon of therapeutic and prophylactic effect of natural mineral waters (MW) used to restore tissue tolerance to glucose and normalize basal insulin secretion in metabolic syndrome is well known. At the same time, the use of selenium-enriched MW is promising due to its multitarget action including participation in the regulation of the protein-synthesizing function of cells.
AIM
To study the effect of internal course intake of selenium-modified mineral waters of different composition on bone mineral density after long-term diet-induced metabolic disorders in the experiment.
MATERIAL AND METHODS
The study was carried out on outbred male white rats that were distributed into 3 control groups (CG) and 4 main groups (MG). In CG1 14 animals received laboratory food and drinking water; in CG2 14 animals were modeled for diet-induced metabolic disorders, and they were withdrawn from the experiment the day after the cancellation of the hypercaloric diet (180 days); after the cancellation of the hypercaloric diet 180 days later 14 animals with diet-induced metabolic disorders in CG3 had a standard diet (laboratory food and drinking water) for 30 days. In the experimental groups (EG), the animals similarly to CG3 were modeled diet-induced metabolic disorders, after the cancellation of the diet they had a standard diet and watering with MW. In MG1 18 animals were given MW1 (Essentuki-4); in MG2 19 animals had a course of MW1Se (Essentuki-4 enriched with selenium); in MG3 14 animals had a course of MW2 (Slavyanovskaya); in MG4 18 animals had a course of MB2Se (Slavyanovskaya enriched with selenium). The weight (body weight) of the animals was monitored monthly. Biochemical studies, densitometry and computed microtomography were used to determine the effectiveness of MW.
RESULTS
The characteristics of spongy bone tissue of femoral metaphysis of the rats of the control groups revealed disorders of varying degrees, but, despite this, the bone tissue structure of the examined vertebral bodies in animals without a hyper caloric diet (CG1) was preserved. The analysis of the study results demonstrated a significant effectiveness of selenium-enriched MW in regulating metabolic processes (p<0.05—p<0.01), bone mineral density (p<0.05), reduced bone resorption (p<0.05), that is, the characteristics of spongy bone tissue of femoral metaphysis and vertebral bodies of animals showed a clear tendency to restore bone structure.
CONCLUSION
The results of this study make it possible to predict an increase in the effectiveness of medical rehabilitation of patients with somatic diseases when selenium-enriched MW is included in the programmes.
